You're never too old (or young) for a great hairstyle and gorgeous makeup, right? That's why we put together these how-tos (obviously!). If you've got a party, anniversary, school dance or even your high school reunion coming up, one of these celebrity hairstyles or makeup looks should do the trick.

Makeup Tip: Have fun with pink like Johansson did. Apply pink shadow (like Bobbi Brown Metallic Eye Shadow in Pink Pearl) on lids and dust a matching pink blush on the apples of your cheeks. Finish with rosy pink lipgloss.
Hairstyle Tip: Pull some of it back with a sparkly hair accessory (check out these celeb hair accessories for inspiration) to show off your face.

Hairstyle Tip: Recreate this messy bun by curling hair with a curling iron before securing it into a low pony. Pin sections of hair around the elastic to form the bun (don't make it perfect, it's supposed to be disheveled). Need more guidance? Follow this how-to. Pull face-framing sections out and smooth with a flat iron (see the best ones here).

Makeup Tip: Line inner rims with black pencil, then sweep a champagne colored shadow on lids. Finish with multiple coats of mascara.
Hairstyle Tip: Get Hudson's piece-y texture by using pomade (try Bumble and bumble Sumowax) to sculpt and flip out your ends after straightening.

Hairstyle Tip: To get this sleek yet slightly messy bun, apply smoothing serum like Frederic Fekkai Glossing Cream, then blow dry hair straight with a paddle brush. Make a deep side part and pull hair back into a low pony. Take random sections of hair (some small and some larger) and pin them around the pony at the nape of your neck.
